Actually NSMBU has two multiplayer modes. 1 requires the pad, and basically lets you like platforms and maybe collect coins on the touchscreen and maybe tap bad guys to stun them, but you don't actually control a character.
The other mode requires you to NOT use the gamepad and is basically just regular old co op.
Is the dev known by trees analysis? That would be hilarious. Imagine. A studio to be shut down after the obvious lawsuit they will lose due to the yakuza nda surrounding nx just because of a tree reflex
I just assume such people never actually played on an n64 which at first makes no sense because everybody did back then, even if they owned a playstation they still will have played on a friends, then I realise I'm old and the n64 gen was 20 years ago and GAF accidentally set it's minimum age as 13 instead of 30 like it should be
If nobody ever did anything crazy or unexpected when it came to controllers, we'd have never moved on from joysticks. I can't imagine that competitive Smash players will be all too happy about this, but I'm sure it works just fine.
Seeing it in black reminds me of one of those "Revolution" controller mockups back in late 2005 / early 2006 that was basically a black SNES controller shaped blob with haptic, light-up blue buttons. It would have been impossibly expensive at the time, of course, but it's interesting that Nintendo could have gone there.
